已知静态的球对称弦带电黑洞有几个与Reissner-Nordström黑洞不同的性质。在这封信中，我们得到了弦荷黑洞的引力能，并观察到总能量是正的，并被限制在黑洞的内部。这与Reissner-Nordström黑洞的结果相反，那里的总引力能是正的，但由其内部和外部共享。因此，与Reissner-Nordström黑洞的情况不同，位于弦带电黑洞引力场中任何有限距离处的中性测试粒子所经历的有效引力质量是正的。
It is known that a static, spherically symmetric stringy charged black hole has several different properties than that of the Reissner-Nordström black hole. In this letter we obtain the gravitational energy of the stringy charged black hole and observe that the total energy is positive and is confined to the interior of the black hole. This is in contrast to the result for the Reissner-Nordström black hole, where the total gravitational energy is positive but is shared by its interior as well as exterior. Consequently, unlike the case of the Reissner-Nordström black hole, the effective gravitational mass experienced by a neutral test particle situated at any finite distance in the gravitational field of the stringy charged black hole is positive.
